Abstract (en)
[origin: EP1132850A2] To enable easy replacement of a soiled fingerprint reading window. To reduce the number of light sources and achieve miniaturization. <??>An aperture 5 is formed in part of a case K constituting the outer shell of a fingerprint recognition device, aperture 5 being covered by a cover member 4. Cover member 4 that covers aperture 5 constitutes part of case K. An aperture 6 formed in cover member 4 is covered by a window member 7 for fingerprint reading consisting of an optically transparent member. Window member 7 is arranged on the under-surface of cover member 4 and is resiliently held by the holding feet 11 formed on cover member 4. Light source 42, light-guide plate 43, reflection mirrors 33 and 34, image pick-up lens 35 and image pick-up element 36 are held by holding body H which is fixedly arranged in case K. Window member 7 is clamped between supporting faces 38 of holding body H and cover member 4 so as to be immovable. <??>Light-guide plate 43 is arranged adjacent and inclined with respect to window member 7. Detection light rays from light-emitting elements 42 are sufficiently diffused while passing through light-guide plate 43 and are emitted in planar fashion from light-guide plate 43 towards window member 7. <IMAGE>
